getdtablesize(3c)

getdtablesize(3C)        Standard C Library Functions        getdtablesize(3C)

NAME
       getdtablesize - get the file descriptor table size

SYNOPSIS
       #include <unistd.h>

       int getdtablesize(void);

DESCRIPTION
       The  getdtablesize()  function  is  equivalent to getrlimit(2) with the
       RLIMIT_NOFILE option.

RETURN VALUES
       The getdtablesize() function returns the current soft limit as  if  ob‐
       tained from a call to getrlimit() with the RLIMIT_NOFILE option.

ERRORS
       No errors are defined.

USAGE
       There  is  no direct relationship between the value returned by getdta‐
       blesize() and OPEN_MAX defined in <limits.h>.


       Each process has a file descriptor table which is guaranteed to have at
       least 20 slots. The entries in the descriptor table are  numbered  with
       small  integers starting at 0. The getdtablesize() function returns the
       current maximum size of this table by calling the getrlimit() function.

SEE ALSO
